Question

carbohydrates

1. name the four important roles of carbohydrates.

Explanation:

Carbohydrates are organic compounds made up of carbon, hydrogen, and oxygen. They play several crucial roles in living organisms. One of their main functions is to serve as a source of energy. When broken down, they release energy that cells can use for various activities. They also act as structural components. For example, cellulose in plants forms cell walls, providing rigidity and support. Carbohydrates are involved in cell - to - cell recognition. Glycoproteins and glycolipids on the cell membrane have carbohydrate moieties that help cells identify each other. Additionally, they can be stored as an energy reserve. In animals, glycogen is stored in the liver and muscles, and in plants, starch is the storage form.

Answer:

Energy source, structural component, cell - to - cell recognition, energy reserve.
